Oncologic outcomes based on lymphovascular space invasion in node-negative FIGO 2009 stage I endometrioid endometrial adenocarcinoma: a multicenter retrospective cohort study.

ABSTRACT:

Background

The 2023 International Federation of Gynecology and Obstetrics (FIGO) staging system includes lymphovascular invasion quantification as a staging criterion for endometrioid endometrial carcinomas; no lymphovascular invasion and focal invasion (≤4 vessels involved) are grouped as one category, and substantial invasion as another.

Objective

To assess the association between lymphovascular invasion and oncologic outcomes.

Methods

We retrospectively identified patients with FIGO 2009 stage I endometrioid endometrial cancer treated surgically with total hysterectomy and lymph node assessment at two tertiary care centers between January 1, 2012, and December 31, 2019. Lymphovascular space invasion was categorized as focal (<5 vessels involved), substantial (≥5 ve
